[Work environment that support workers with diseases to maintain a work-treatment balance in Ishikawa prefecture: relationship with company scale and type of industry].

Objectives: We investigated the support environments in companies in Ishikawa prefecture that aim to maintain a balance between work and treatment of their employees' diseases. The relationships between these strategies, company size, and type of industry were examined.

Methods: In 2016, as a part of a survey, questionnaires were sent to 1,491 companies with ≥ 50 employees. Of the 688 companies who responded (response rate, 46.1%), 624 companies who provided complete main survey data were included in the final analysis. The questionnaire acquired responses on systems for arranging working hours and sick leave, the role of occupational health physicians, and the outcomes of support that was offered over the last 3 years. The targeted diseases were mental health problems, such as depression, and physical diseases. Responses were compared according to the size of the company and type of industry.

Results: A total of 409 companies (65.5%) reported their experiences of helping employees maintain a balance between treatment and work over the last 3 years. Employees with depression received the most support. In 36.7% of the companies, some employees had retired due to their disease over the last 3 years, with the highest proportion in medical care and welfare businesses. Further, 66% of the companies had a support system to help employees with diseases, and the proportion of companies with flexible working hours and sick leave increased with the number of employees. The proportion of companies with shorter working hours and hourly paid leave was lower in the manufacturing industry and transportation/traffic business. The proportion of companies in which an occupational health physician interviewed employees who took sick leave and returned to work was 22%.

Conclusions: Almost 70% of the companies reported supporting workers during their disease treatment. There were some differences in arranging these support systems between companies of varying sizes and type of industry. The enablement of companies to support workers with diseases so that they keep working and receive treatment requires consideration of company characteristics.
